Power

The Integrator/Multiplexor board receives +/-15V and +5V from the Analog To Digital board.
The +/-15V is passed through this board to the Solid State Detector boards. Voltage regulators,
located on this board, convert this voltage to +/-12V to power circuitry contained on this board.
Analog and digital returns are kept separate.

Interface Connections

Figure 2-16 shows the interconnections between the Analog/Digital Converter board and the
Integrator/Multiplexor board. Table 2-22 describes the interface signals and identifies the
interconnection connector and pin assignments.
